This could result in severe patient complications during and after surgery. This also makes surgical visualization in the bloody field difficult and the duration of surgery more prolonged. With the new anesthetic agents, drugs, and monitoring techniques, this problem has been addressed. Controlled hypotension is defined as a reduction in systolic blood pressure to 80–90 mmHg, a reduction of mean arterial pressure (MAP) to 60–70 mmHg or by 30% of the baseline. Controlled hypotension is a commonly used technique to limit blood loss and improve visualization of the operative field during vertebral fixation surgery. Objective To compare the effects of intravenous infusion of dexmedetomidine (DEX) and nitroglycerin (NTG) on intraoperative hemodynamics, amount of blood loss, speed of recovery from hypotension after cessation of infusion, and postoperative complications. Subjective This study was carried out on 50 adult patients of both sexes, American Society of Anesthesiologists I and II, admitted to Alexandria Main University Hospital, Department of Neurosurgery for elective spinal fixation surgeries (by the same surgical team) under general anesthesia. Results The results of the present study showed that arterial blood pressure in group I DEX at baseline (before induction of anesthesia) was 87.32±6.11 and increases significantly after 10 min from 20 to 80 min. The MAP was significantly decreased in group I at 90 min till the end of follow-up; there was no significant change in MAP from the baseline, while in group II ‘NTG.’ Comparing the two studied groups regarding MAP at different periods of follow-up, it was found that there was no significant difference between the two groups regarding MAP all over the period of follow-up. Conclusion NTG and DEX could induce hypotension, but DEX showed a more favorable hemodynamic profile as regards blood pressure and heart rate. DEX also showed a shorter duration of surgery with less blood loss and less blood transfusion.","PeriodicalId":151256,"journal":{"name":"Research and Opinion in Anesthesia and Intensive Care","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132338950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The duration of the spinal anesthesia has been improved by the addition of other drugs such as opioids, dexmedetomidine, clonidine, and dexamethasone. Dexamethasone may affect blood glucose levels. The primary outcome of the study was the effect of a single dose of intrathecal dexamethasone on blood glucose levels during the first 24 h postoperatively. Patients and methods After approval, 60 diabetic patients, American Society of Anesthesiologists grades 2 and 3 with ages ranging from 20 to 70 years were enrolled in this randomized, double-blinded, placebo-controlled trial. All patients who underwent diabetic foot surgery under spinal anesthesia have controlled type II diabetes. Patients were randomly allocated into two equal groups: the control group was given intrathecal 2.5 ml of hyperbaric bupivacaine 0.5% plus 1 ml of 0.9% sodium chloride. The dexamethasone group was given intrathecal 2.5 ml of hyperbaric bupivacaine 0.5% plus 4 mg of dexamethasone. Results The control group had significantly lower levels of blood sugar at different times compared with the dexamethasone group. However, at the end of 24 h, nonsignificant changes were present between the two groups. Also, using 200 mg/dl as a cutoff for high blood sugar, there were nonsignificant changes all through the 24 h in both groups. Moreover, dexamethasone prolongs the duration of analgesia and decreases paracetamol requirements during the first 24 h postoperatively. Conclusions Addition of intrathecal dexamethasone did not change postoperative glycemic evolution in controlled diabetic patients undergoing diabetic foot surgery. However, it significantly prolongs the duration of analgesia and decreases analgesic consumption during the first 24 h postoperatively.","PeriodicalId":151256,"journal":{"name":"Research and Opinion in Anesthesia and Intensive Care","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122773929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Neostigmine has been used as an adjuvant to local anesthetics, but the existing research studies are few. This study was conducted to evaluate the efficacy of neostigmine as an adjuvant to local anesthesia used for PVB in inguinal hernia repair procedures. Patients and methods This prospective randomized study included 72 patients prepared for elective inguinal hernia repair under PVB. They were allocated into two groups: the neostigmine group received a mixture of bupivacaine and neostigmine (5 μg/kg), whereas the control group received bupivacaine alone. During the postoperative period, pain score, hemodynamic parameters, first analgesic request, total analgesic consumption, and the incidence of adverse effects were noted and recorded. Results Both groups showed comparable findings regarding age and weight. However, the number of patients requiring rescue analgesia showed a significant increase in the control group. Moreover, controls reported significantly earlier first analgesic requests. Both diclofenac and fentanyl consumptions were increased without neostigmine administration. Pain score was significantly better with neostigmine at 4 and 6 h after surgery. Hemodynamic parameters were almost comparable between the two groups. Conclusion Neostigmine appears to be an efficient adjuvant to local anesthetics when administered during PVB as it significantly improves its analgesic profile. Its administration should be encouraged in clinical practice.","PeriodicalId":151256,"journal":{"name":"Research and Opinion in Anesthesia and Intensive Care","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128990555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is considered that artefacts generated by lung ultrasound (LUS) can help in diagnosis and management. FALLS-protocol using LUS is a tool proposed for the management of unexplained shock. Objectives To investigate the role of LUS FALLS-protocol in differentiating types of shock in critically ill patients. Patients and methods A total of 50 patients presented with undiagnosed shock. Fast bedside echocardiography and LUS FALLS-protocol were applied along with inferior vena cava diameter and collapsibility measurement. Results A total of 19 patients with septic shock on presentation had A profile in all of them and AB profile in three of them, and after resuscitation, they were transformed to B profile with 100% sensitivity, 90.5% specificity, 90.5% positive predictive value (PPV), and 100% negative predictive value (NPV). Overall, 16 patients with hypovolemic shock had A profile in all of them on presentation and after resuscitation, with 100% sensitivity, 94.1% specificity, 88.9% PPV, and 100% NPV. Moreover, eight patients with cardiogenic shock had B profile in all of them on presentation with 100% sensitivity, 95.2% specificity, 80% PPV, and 100% NPV; three patients with obstructive shock had A profile in all of them on presentation, with 100% sensitivity, 25.5% specificity, 7.9% PPV, and 100% NPV; and two patients with anaphylactic shock had A profile in all of them on presentation and transformed to B profile after resuscitation with 100% sensitivity, 50% specificity, 9.5% PPV, and 100% NPV. Our findings showed preference of FALLS-protocol than inferior vena cava diameter and collapsibility in directing fluid therapy.

The aim of this study was to compare the onset time and intubating conditions at 90 s using 0.3 mg/kg cisatracurium (6× ED95) versus 1.2 mg/kg rocuronium (4× ED95). Material and methods The study was conducted at a tertiary care hospital as a randomized double-blind prospective study after obtaining the ethical committee clearance. A total of 60 patients were randomly assigned to receive 1.2 mg/kg rocuronium (4× ED95) or 0.3 mg/kg cisatracurium (6× ED95) after premedication with fentanyl-midazolam and induction with propofol-sevoflurane. Laryngoscopy and intubation were done at 90 s. Primary outcomes assessed were laryngoscopy and intubation conditions and onset times. The Student t test was used to compare prospective, repeated measures. χ2 test was used to test the significance of difference for qualitative variables. Results The onset of action of the muscle relaxant was predicted by measuring train-of-four ratio and was found to be significantly longer in the cisatracurium group (149.50±25.064 s) than in the rocuronium group (101±s) (P<0.05). Although the intubating conditions were better in the rocuronium group, cisatracurium also provided good to excellent intubation conditions at 90 s. Conclusion Cisatracurium can be used to intubate the trachea at 90 s at a dose of 0.3 mg/kg in patients premedicated with fentanyl-midazolam and induced with propofol-sevoflurane, while maintaining hemodynamic stability, without increasing the incidence of adverse effects.","PeriodicalId":151256,"journal":{"name":"Research and Opinion in Anesthesia and Intensive Care","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114146132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim To study the effects of mixing local anesthetic with either dexmedetomidine or fentanyl in the peribulbar block for vitreoretinal surgery. Patients and methods The study included 40 adult patients (ASA II–IV) who had a peribulbar block for elective retinal surgery at Sohag University Hospital. All patients received the following combination: lidocaine 2%, bupivacaine 0.5%, hyaluronidase 15 IU/Ml, in addition to either 20 μg of fentanyl (group F) or 20 μg of dexmedetomidine (group D). The duration of postoperative analgesia, the onset, and duration of sensory and motor blocks, along with other complications, were recorded. Results The onset time of motor and sensory blocks was significantly longer in group F. For the duration of sensory and motor blocks, group D had a significantly greater duration than group F (P=0.05). Group D took substantially longer to request analgesia than group F (P=0.0002). Total paracetamol consumption was substantially higher in group F than in group D (P=0.001). The overall number of patients who required nalbuphine was substantially higher in group F (P=0.003) than in group D.
